For With Fire and Sword expansion, this adds denser flora. I don't quite care for the look at the moment, but it's just some .txt hacks, so it's the best I can do until they release the module system stuff. To install:

Place the file in: Program Files/Mount&Blade With Fire and Sword/Modules/Ogniem i Mieczem/Data, or Program Files/Steam/steamapps/mount & blade with fire and sword/Modules/Ogniem i Mieczem/Data
